[dpdk-dev] [PATCH 12/29] ixgbe/base: fix error path to release lock

[Beilei Xing <beilei.xing@intel.com>]

When there is an error getting the PHY token, the error path
fails to release the locks that it has taken. Release those
locks in that failure case.

Fixes: 86b8fb293fdf ("ixgbe/base: add sw-firmware sync for resource sharing)
